Pedigree
Thirty years of making cars handle better than they were built to.
Ridetech started in 1996 with air suspension controllers and grew into a full engineering house: chassis, subframes, coil-overs, control arms and shocks—all designed, tested and built under one roof in Jasper, Indiana. In 2018 we joined the FOX Factory family, pairing our chassis expertise with damping technology proven on the street, the test track and in competition.
